STOPPER FOR BOTTLES AND OTHER-RECEPTAGLES No. ss5,74a.

To altivhom it may concern! Be it known that we, LIONELLO GANUOCI- subie'cts of the King of Italy, residing at fill Improvements in Sto pers for Bottles and other Receptacles, of W iich the following is a specification.

This invention has for its object the closin of'any receptacle containing li uids or so 'ds of no matter what kinds Whic areto that they cannot be 0 ened without break-f It is based on the princi le of the introduction into a chamber provi' ed in the neck of the "flask, or any leavesameagain. v M Consequently the invention consists in receptacle to which it is permanently connected and which is called the"chamber, while the .other, which ismovable and inde- The-accompanying drawings llustrate the tion, the neck of the ottle, or of any other receptacle in which the above mentioned Fig. 4 is a bottom view ofone portion of'the diaphragm; Fig. 5 is a section thereof; Figs. 6 and 7 show a bottomview and asection, respectively, of the other part of the diaphragm; Fig; 8 shows an opening tool.

The chamber a is constituted'by an exterior enlargement of the wall forming theneck bof the flask or any other receptacle.

and considering it only in relation to its essential organs for the operation, is composed of two parts or two t posed one over the other, of metal, or any other'suitable material.

The upper part of the diaphragm illustrated separately in Fig. 4, from the underside, and in Fig. 5, in section,serves also as a guide to the-lower part; with this object, it has its lateral edges (1, cl turned down underneath. It moreover bears towards one of its extremities a bend e, having the form of a sawtooth, which presents the hollow to the upper face and a corresponding projection on the opposite side. .printed any marks which may be considered desirable.

The lower part of the diaphragm, illustrated separately, from the under side, in Fig. 6, and in section in Fig.- 7, also consists in a sheet which as a Whole (that is to say with regard to area and form) is almost identical. Withthe upper part; but it is formed in the following manner: It bears at one of its extremities a'small tail which serves as a point of pressure when it is desired to slide one sheet on the other and permits, therefore, of imparting to the diaphragm its maximum lengt afterit has been introduced into the chamber. At its up osite extremity it carries'- three tongues, t e two lateral-and fiat ones '9, g, of which are lIltIOdi ced into the folded over ed es (1, d, of the other sheet and serve as a gui e for the third (tongue) central' one it, slightly curved upwards and formed throughout its lengthwith a rib which serves to strengthen it and to increase its elasticity, for it is to act as a spring.

Operation. After the flask, or any other receptacle, has been filled and stoppered if it is necessary, with the cork i, so that the chamber in the neck remains completely empty and free, into such chamber is introduced the diaphragm with the sheets exactly superposed so that they present the smallest area and that it may be ossible to introduce them. Then, by hol ing the u per sheet stationary and by means of a sma tool pushinglagainst the tail f of the under sheet, they be caused to slide one over theother, un-

til the central tongue it has passed over the projection formed by' the tooth 6. Then, the iaphragm will occupy the entire interior surface of the chamberand it can no longer be Withdrawn therefrom, without the edges of the chamber being broken, because the cenn sheets, super--' on the upper face may be tral tongue h, pressing against the tooth e, presents an absolute obstacle-to the sheets of the diaphragm being superposed. It must be added that (when it is a question of a flask entirely of glass) for facilities of carrying the chamber and the dia hragm, the inventors have thought of ma ing a circular partial incision Z, on the exterior surface beneath the chamber a of the flask. This incision, which for-a very small part of its travel is accentuated in such a Way that it becomes complete and forms a hole p, which renders the racturing of the 11 per part of the flask or any other receptace easy, by means of a suitable tool illustrated in Fig. 8. This tool is formed with a ring n, into which the whole of the u per part of the flask can pass. Consequently in the case of an elli tical chamber, it will be made elliptic; but t e chamber being of another form, the tool must be such that the upper part of the flask or other re-' ceptacle, may enter it. After having introduced the head of the flask or receptacle, into the ring n, the ring is turned, causing it to make one quarter of a revolution; then the ring can no longer be withdrawn. By causing the point 0 to enter the hole p and employing the handle g as a lever, the neck of the. flask, or other receptacle, will be fractured exactly along the lineof the incision; conse gently, the part of the neck which contains tihe chamber a with the diaphragm, can be removed with facility; after which the cork situated therein is withdrawn by a corkscrew. The handle q may be made in the form of a corkscrew (Fig. 8) so as to require a single tool instead of two. After having resssnes moved the chamber from the neck of the receptacle, the whole of the closing apparatus is missing, consequently, it evidentl follows that the receptacle has been broken and opened; however the receptacle may be still used as an ordinary receptacle. The neck of the flask may be formed with a second rim m, for strength. but this is not indispensable.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, with a vessel having an orifice to be stopped, provided with interior shoulders, a sto per adapted to close said orifice and means or preventing the withdrawal of said stopper, said means comprising two parts, one sliding on the other and adapted to engage with the interior shoulder when expanded, and means for locking the parts in their expanded position.

2. A bottle having an annular groove in its neck, a stop er for the bottle and means for reventing t e withdrawal of the stopper, said means consisting of two interlocking parts, one sliding on the other and adapted to e expanded to engage the groove, each art having a projecting portion thereon w ich engage with each other to lock the parts in their expanded position.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
